Introduction
Congratulations on your purchase of the MN47 MultiMeter. The MN47 offers AC/DC Voltage, AC/DC
Current, Resistance, Diode, and Continuity and Temperature. Proper use and care of this meter will
provide many years of reliable service.
Safety
This symbol adjacent to another symbol, terminal or operating device indicates
that the operator must refer to an explanation in the Operating Instructions to
avoid personal injury or damage to the meter.
This
WARNING
symbol indicates a potentially hazardous situation, which if not
avoided, could result in death or serious injury.
This
CAUTION
symbol indicates a potentially hazardous situation, which if not
avoided, may result damage to the product.
This symbol advises the user that the terminal(s) so marked must not be
connected to a circuit point at which the voltage with respect to earth ground
exceeds 600V.
This symbol adjacent to one or more terminals identifies them as being associated
with ranges that may, in normal use, be subjected to particularly hazardous
voltages. For maximum safety, the meter and its test leads should not be handled
when these terminals are energized.
SAFETY INSTRUCTIONS
This meter has been designed for safe use, but must be operated with caution. The rules listed
below must be carefully followed for safe operation.
1.
NEVER
apply voltage or current to the meter that exceeds the specified maximum:
Input Protection Limits
Function Maximum
Input
V DC or V AC
600V AC and DC
mA AC/DC
400mA DC/AC
A AC/DC
10A DC/AC (for 30 seconds max. every 15 minutes
Frequency, Resistance, Capacitance,
Duty Cycle, Diode, Continuity,
Temperature
250V DC/AC
2.
USE EXTREME CAUTION
when working with high voltages.
3.
DO NOT
measure voltage if the voltage on the "COM" input jack exceeds 600V above earth ground.
4.
NEVER
connect the meter leads across a voltage source while the function switch is in the current, resistance, or
diode mode. Doing so can damage the meter.
5.
ALWAYS
discharge filter capacitors in power supplies and disconnect the power when making resistance or diode
tests.
6.
ALWAYS
turn off power and disconnect test leads before opening the covers to replace the fuse or battery.
7.
NEVER
operate the meter unless the back cover and the battery and fuse covers are in place and fastened securely.
8.
DO NOT
use the meter if the meter or test leads look damaged, or if you suspect the meter is not operating properly.
9.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may
be impaired.
